IMPROVEMENT IN BORING-FAUGBTS.

'T0 ALL WHOM IT MAY CONCERN:

Be it known that we, J oTHAM R. LAWRENcE aud-IsAAc G. JOHNSON, of Cutler, in the county of Washington, and State of Maine,.have invented a new and valunblelmprovement in Faucets; and we do hereby declare that the.. following isafull, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this speclicaton, and to the letters and figures of reference marked thereon. l

Figure 1 of the drawings is a representationof a side elevation.

Figure 2 is a section through the centre, (longitudinal.)

Figure 3 is a back elevation.

Figure 4 is an elevation of the gate.

Similar letters of reference indicate like parts.'

This invention consists mainly in attaching to a faucet of the usual style a boring-tool and core-chamber,

also an arched clamp,.hy which the gate is kept perfectly rigid to the lever, audolose upOn the face of the faucet.

A represents the body of the faucet; B, the-core-chamber; C, the boring-tool'or bit; D, a partition, which separates the body of the faucet from the core-chamber, and'in which the shank of the boring-tool .is fixed. rEhe holesl a aa a communicate vwith the body of the faucet, and the insdeof the vessel in which it is placed.

E represents the arched clamp, through which the thumb-screw G passes into the lever F; H, gate, and o o o o cleats upon the gate, forming shoulders, upon which thel edges .of the lever bear in raisingor lowering the gate; I, pin by which the leve;1 is fastened, and upon which it turns.

X represents a section of the end or wall to which the faucet is attached Operation.

l The bit C must be suitedto boring'a hole exactly the diameter of the outside of the core-chamber B, which, with the partitionA D,vfor'ms astopple. After the hole is bored, it is then pushed into the screw-thread, and turned in the usual manner until the holes a a @pass entirely through the end or wall of the vessel, as represented by section X, forming a communication, as shown by the arrows. Y

The clamp Eis operated by the thumb-screw G lpassing loosely through it, and bearing ,upon the shoulder C,- and tapping into the lever F. It will appear, by inspection (see g. 2) the ends of the clamp E and screw Gr, all bear upon the gate H, the screw passing entirely through the lever, thereby forming three bearings, by which the gate is kept close upon the face and rigid upon the lever.

We claim, and desire to secure by Letters Patent- A faucet having boring-tool C, core-chamber B, clamp E, thumb-screwGr, lever F, gate H, pin I, and cleats o, constructed, combined, and operating substantially as specified.

In testimony that we claim the above, we have hereunto subscribed our names in the presence of two -Witnesses.
